摘　　要：目的 探讨关于使用径线法评估脑白质高信号(WMH)相关脑萎缩严重程度的可行性。方法 回顾性选择2023年9至10月扬中市人民医院临床检查者和健康体检者131例,按WMH严重度分组并测算各组的双尾状核指数Evans指数及哈氏值、第三脑室宽度、脑室指数、侧脑室体部指数、外侧裂宽度。对各组所测经线指标进行单因素方差分析,评估不同WMH严重度时脑萎缩情况是否存在差异。结果 不同WMH严重度的受检者其哈氏值、第三脑室宽度、脑室指数、侧脑室体部指数、Evans指数、双尾状核指数及脑沟宽度存在统计学差异。组间多重对比结果显示仅双尾状核指数在不同WMH分组间差异均有统计学意义。结论 径线法可以评估WMH相关的脑萎缩严重程度,常用的径线指标中双尾状核指数对WMH相关的脑萎缩最为敏感。Objective To explore the feasibility of using the linear measurement to evaluate the brain atrophy and study the relationship between hyperintense signal severity and brain atrophy.Methods One hundred and thirty one patients were collected from clinical examiners and health examiners in Yangzhong People′s Hospital from September to October 2023,grouped by the severity of WMH,and the bicaudate index,Evans index,huck number,third ventricle width,ventricular index,cella media index,and lateral fissure width were measured and calculated in each group respectively.One-way ANOVA was performed on the linear indexes in each group to assess whether there were differences in brain atrophy by WMH severity.Results There were statistical differences in huck number,third ventricle width,ventricular index,cella media index,Evans index,bicaudate index,and lateral fissure width among subjects with different WMH severity.The results of the multiple comparison analysis showed only the bicaudate index varied between groups.Conclusion Linear measurement can roughly assess the severity of brain atrophy with the severity of WMH.Bicaudate index in commonly used linear indexes may be sensitive to brain atrophy associated with WMH.
